What is an oil free screw compressor?

Oil-Free Screw Compressors: Uses what is called synchronised timing gears, the gears ensure that the screws rotate without making direct contact with each other, removing the need for oil lubrication. This helps keep the compressed air clean and reduces maintenance complexity.

Why are oil-free screw compressors important?

Oil-free screw compressors are vital for industries needing clean, contamination-free air. This guide explains their importance, working principles, cooling techniques, and benefits, ensuring optimal performance in applications with stringent air purity requirements. Contact us!

What is an oil-free compressor?

Oil-free compressors are most commonly used in applications that demand the highest quality air, and/or applications that can’t tolerate any risk of gross oil contamination. Oil-free compressors still have oil inside them! Re-using existing tanks or piping? Use of bypass piping?

Why are oil-free compressors important?

Oil-free compressors eliminate this risk altogether. By ensuring absolutely no oil is introduced into the compression chamber, they deliver 100% oil-free compressed air, making them indispensable in applications where air purity is critical. How Do Oil-Free Compressors Work?

Do screw compressors need oil?

A key challenge for oil-free screw compressors is managing the heat generated during compression. In oil-injected compressors, oil acts as both a lubricant and coolant, but this option isn't available in oil-free designs. Without oil for cooling, temperatures can rise quickly.

How do oil-free screw compressors work?

The solution is multi-stage compression. Instead of compressing the air in a single step, oil-free screw compressors use multiple compression stages. The air is cooled between each stage, preventing excessive temperature buildup and ensuring efficient operation.
